Oysters could help protect coastlines against storms and sea-level rise

Experts say restoring oyster reefs could provide a natural buffer against coastal erosion and storm damage as sea levels rise.

Catherine Zhu reports for CBC.

In short:

• After Hurricane Sandy, New York launched a project to rebuild oyster reefs as wave barriers, with Canada exploring similar methods.
• Oyster reefs can naturally grow over time, unlike static infrastructure, making them ideal for long-term coastal protection.
• Regulatory challenges in Canada, including concerns over shellfish diseases, have delayed restoration efforts despite the proven benefits of oyster reefs.

Key quote:

"It was the first time I'd come across the messaging needing to change from, 'we need to get our emissions to reduce,' to 'we need to start trying to protect lives."

— Tim Green, fisheries and aquaculture professor at Vancouver Island University

Why this matters:

Oyster reefs offer a sustainable way to shield coastlines from storm surges and erosion. As climate change accelerates, finding nature-based solutions like these could save lives and preserve vulnerable ecosystems.
